Problems solved by technology

At present, the traction ratio of large-tonnage traction elevators is mostly 4:1 structure, but the elevator traction machine produced and developed by domestic enterprises has a maximum load of 2500k and a speed of 2.0m / s. If the 4:1 rope winding structure is still used, then The load of the elevator can only reach 10,000kg, and the elevator with a load of more than 10,000kg cannot meet the requirements

Abstract

The invention relates to a large-tonnage multi-winding-ratio traction elevator, wherein the elevator comprises an elevator car, a counterpoise and a rope wheel lifting mechanism; the rope wheel lifting mechanism comprises a driving control system containing a tractor inside, and a counterpoise-side fixed pulley block and a car-side fixed pulley block, which are installed in a motor room, a car-roof rope wheel set installed on the elevator car, and a counterpoise rope wheel set installed on the counterpoise, wherein the traction ratio of the elevator is 2n:1 in which n is a positive integer more than or equal to 4; and the tractor is installed in a motor room, and the shadow position of the tractor is in the middle in the depth direction of the elevator car. The invention has the following beneficial effects: (1) adopting a rope winding structure with the traction ratio of more than 8:1 to increase the elevator load lifted by the tractor to be more than 30,000 kilograms; and (2) distributing the tractor in the middle of the elevator car, thereby effectively reducing the deflection amount when the elevator is started.

Description

technical field [0001] The invention relates to a large-tonnage multi-winding-ratio traction elevator, in particular to a multi-winding-ratio traction elevator with a carrying capacity of more than 30,000kg at one time. Background technique [0002] With the continuous development of the social economy and the continuous improvement of the level of industrial automation, the demand for large-tonnage freight elevators in many fields of industrial production is increasing. At present, the traction ratio of large-tonnage traction elevators is mostly 4:1 structure, but the elevator traction machine produced and developed by domestic enterprises has a maximum load of 2500k and a speed of 2.0m / s. If the 4:1 rope winding structure is still used, then The load of the elevator can only reach 10000kg, and the elevator with a load of more than 10000kg cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies...
